This invention relates to furniture for ofiices, banks and the like, and more partlcularly to an improved bookkeepers desk which l maybe 5 sitting position.

A primary object of the invention is to provide a desk which includes storage space for the files, booksor papers, and also has a novel topl construction whlch provides an increased 1o area or working surface for the desk.

' vAccordingly, the present invention contemplates, in its specific aspect a novel top construction Iincluding extensible sections adapted for relative sliding telescopic movement in a simple and practical manner to provide more space as desired. c c

Withthe above and other ob]ects in v1ew which will more readilyappear as the nature of the invention is better understood, the

same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which: y

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

According to the embodiment of the invention shown in the drawings, there is provided a desk structure designated generally as D and including a working surface or top A which surmounts the drawers'B for receiving papers, files, records or the like. In that conused with the bookkeeper assuming a BooxxEErEns Dnsx 192s. serai mi. 294,005.

nection, however, it will of course be understood that the top A may be used with or without the cabinet features referred to, the embodiment shown being merely an example of the range of utility of the novel desk top or table construction constituting the subject matter of the present invention.

The top A is primarily designed to give more or less working surface according to' the requirements of the user and yet at the same time normally occupy a minimum space. The said top `A which constitutes the normal working surface of thev desk is substantially co-extensive with the entire desk or cabinet and when in the position shown in Fig. 1 houses and conceals asub-topAtherebeneath. The main top A is therefore slidably mounted to be moved back and forth to vary the area of the working surface as will be apparent from an inspection of Figs. 1 and 2, the latter figure showing the main top section pulled completely forward to expose the sub-top A which is automatically moved up into surface alinement with the main top A, as will hereinafter more fully appear.

Also, if desired, the desk maybe provided with a laterally offset top section A2. This is a normally stationary or fixed top portion which is adapted to be especially of use to an operator using an adding machine, a portion of the machine fittingfbehind the offset top A2 so that the latter will provide a support pr slelf for checks or other papers being tabuate From the foregoing it will be apparent that the present invention primarily contemplates a pair of top sections A and A which have a relatively telescopic relation sov that the may be stacked or nested when only the or inary desk top space is necessary, but which may beextended horizontally when desired to provide an increased surface or desk top area by the mere act of relatively sliding one section with reference to another.

Referring now more particularly to the details ofconstruction for carrying the above into effect, it may be observed from Figs. 3,4 and 5` that the main top section A includes a pressed metal body portion 1 having its top surface covered with linoleum or the. like 1W 2. The sides of the body 1 are formed with the inwardly turned channel portions 3 whose inner walls 3 serve as guide walls when engaging the combined guiding and stop abutments et carried by the base 5, whereb .the main top section A may have a free slldlng movement on the base 5. The said walls 3. of the body l carry the angle members et whlch engage the abutments 4 when the main top is pulled out as shown in Fig: 3 to prevent 1 ts disengagelrrent from the cabinet. flhe main top section A also carries at one side there-l of an ornamental facing strip 6 so that when the main top section A is extended as shown in Fig. 2 the edge thereof adjoining the stationary top A2 will have the same faclng as the front edge 7 of the extensible top and the front edge 8 of the stationary top section A2. The main top section is further provided at the side thereof, opposite the facing strip 6, with a guard member 9 of angular cross section which provides an upstanding exposed guard wall 10 and an intermediate horizontal shoulder 11 adapted to lie beneath the offset portion 12 of the side wall W of the cabinet. The upper portion W of the sald wall 1V is co-extensive in height with the guard wall 1() of the movable section A and extends entirely around the side and back edges of the cabinet, thereby to provide a continuous horizontally disposed offset portion 12 around the rear of the desk or cabinet which constitutes an abutm-ent for the sub-top section A as will presently appear. The object of this offsetting 12 at the intermediate portion of the wall 1V is to prevent papers from falling into the space that would otherwise exist between the sub-top A and the edge wall of the desk.

Referring now more particularlyto the sub-top A which is adapted to be depressed and held in a concealed position by the main top section A, it will be observed from Fig. 5 that the said sub-top section A consists of a body portion 13 having a linoleum or equivalent top covering 14, while the underside is fitted with the channel members 15 which carry the spring guide posts or bolts 15l having thereon the coiled springs 17. The opposite edge portions of the body 13 are provided with bronze side rails 16 whose upper surfaces are normally held in engagement with the underside 4of the base 1 when the top sections A and A are in overlapping relation due to the fact that the sub-top A is continually urged upwardly by the said springs 17. -These springs are mounted at suitable points beneath thel base 13 of the sub-top as will be apparent from Figs. 3, 4 and 6 so that when the main top section A is moved forwardly to clear the sub-top, as shown in Figs. 2 and 3, the said sub-top will automatically move upwardly until the bronzed rails or shoes 16 at the sides of the sub-top A engage with the offset portions 12 of the side walls of the cabinet. When the top main section A is extended as shown in Figs. 2 and 3, the top surfaces 2 and 14 respectively of the main top section A and the sub-top section A automatically come into surface alinement to give the extended desk top surface clearly shown in Fig. 2.

When it is desired to return the desk to toits normal position as shown in Fig. 1, 1t is only necessary to depress the sub-top section A by hand pressure until it is low enough to permit the main top section A to slide back over it. The main top section A may then be pushed over the sub-top section as'clearly shown in Figs. 1 and A thereby to bring the sections into relatively telescopic or collapsed relation. On the other hand, when it is desired to provide an extended top or augmented working surface, it is only necessary to pull the main top section A forwardly until the sub-top A jumps into position.

lWithout further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.
